Broke my damn thermister

I have the Big and have only been using one print head, even tho I have the dual extruder.I wanted to get used to the single before trying the dual.While putting the parts together I noticed a lot of build up on the nozzle and underside of the heating block.I decided to clean it before mounting it to the dual plate and SNAP there went the thermistor right at the block.Half in and half out no fixing it.So I decided to use the extruder I have not used and it is out of wack....It wont regulate the temp, I had it set for 210 for the first test and it went up to 268 before I noticed.Every time I try to heat it it just keeps going up, there is no stopping it until I kill the power........So now I have no extruders that work!!

Went to Inventa Part, guess they dont have parts for sale yet.Going to Ebay now.....
